Hi Bruce,
Sorry! I send the wrong patch, it is the old one.
Please discard this patch. I will send the new one in later.
Thanks,
LImeng

> Intel Stratix10 is very the same with Agilex platform, the DWC2 IP on the

> platform also does not support clock-gating. So, based on commit

> tree,
> keep compatible string "intel,socfpga-agilex-hsotg" unchanged.
